I just put together my rig and everything seemed to be alright. I decided to run a prime 95 test on my computer and the CPU would instantly jump from 28c at idle to 100c. I have the Corsair H60 and my CPU is the i7-4790k. I already checked to make sure that my pump is getting the 12V of power it needs and I already tried reseating the cooler. The pump and fan are both working fine. If you guys have any idea what I can do to fix this, I'm all ears.
 
Is the Bios up to date? I had issues with my GENE-Z MB as the board was pumping too much voltage through as it could not recognise the chip making it throttle almost immediatly on the stock cooler, once updated the temps were hitting 89c at stock.after 3hrs of prime.

Try manually setting vcore in the bios too, some have an offset which pumps and extra 0.1v through the chip, manually setting the vcore disables this offset.

I have a 4790K on a H100i and it idles about 2c above ambient,

under load at 4.4Ghz 1.132vcore it hits 60c after 3 hrs prime max heat
At 4.6Ghz 1.2vcore it hits 71c after 3hrs prime95
at 4.8Ghz 1.28vcore it hits 82c under prime 95 after 3hrs

This is in summer temps of 25c ambient

Edit - I also installed rubber o rings when i installed the backplate of the H100i, in the correct orientation, to give a truer mating surface between CPU and heatsink.
 


What should I set the vcore to? When i set it to 1.132V and ran Aida64 I got a bsod after 40 seconds or so.
 


Is the bios the latest version, no point doing anything until that's done.

You need to find your own vcore, just bump it a little and try again, keep going until it's stable for a few hours, try 1.14v, then 1.15v etc etc
 




Yeah the bios is up to date and is compatible with my chip. I'll try finding my own vcore and I think I'm gonna turn off the K overclock, perhaps that will help lower the temperatures more.
 
It has been discovered that for some reason the mounting pressure on a pump has a definite bearing on its ability to absorb the cpu heat. All cpu coverings whether pump or block or aircooler, need to be solidly mounted to the lid, but with aircoolers this is to what's considered 'tight'. With blocks and pumps you get measurably better results if the mount is what to aircoolers considered 'over tight'. Aircoolers are only supposed to be tightened by hand down to 'its starting to hurt the fingertips now' whereas pumps work better at 'ok, get the screwdriver and add an extra 1/4 turn' passed that. In the article i read, which I can't seem to find now, there was an almost 10° difference between the instructions recommended and the 'over tight' reality.
 
I have question about h60 max i go with h60 is 70C which is good. But the H60 make some terrible annoying noise isit normal? is my first cooler so idk if is normal or not it does it since the beginning
